i Specification of Letters Patent.

Applicatilin filed b r 6i1906 Serial No. 34 21258- To all whom it may concern:

Be 1t known that I, WLADIMIR NOFF, a cltizen of the Russian Empire, residing at St. Petersburg, Russia, have lnvented certain new anduseful Improvements inHydraulic Presses; and I, do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains' to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which "form a part of this specification.

This invention has for its object a pistonless press foruse with fluids-under pressure such as water, gas, steam, in which high pressure is obtained not by an increase in the tension of the working fluid but mainly by an increase in pressure surface; this avoids the use of very'costly and complicated accesso ries (such as the compressor, high pressure accumulator, and especially pipes capable of withstanding high pressure) of the hydraulic.

presses at present in use which work often with a pressure as great as from 200-300 atmospheres.

In a oress constructed according to the present invention inplace of the hydraulic cylinder there is usedv a bellows like receiver whose rigid upper (or lower) endsurf ace or cover for performing the press action, s t e entrance of the pressure fiuld which open out. If the folds of .the bellows are not made large and proper care is taken for the stifiening of thesame, the cross section of the container may he as large as desired, without fear of bursting the bellows as the ressure of the working fluid is low.

The accompanying drawings illustrate the invention. I

The upper end 3of the folding receiver 1 carries one press plate 2 of the press and is provided with stufling boxes 18 of any suitable construction for the assa e'of the columns 13, which are fixe to -t e bed-plate carry the upper press plate 2 which may be immovable or made adjustable to various levels by any well known meanst The re ceiver 1 is supplied with fluid through the pipe 4 and can pipe 5 which is provided witha cut ofi are rangement of any suitable. construction not shown in the drawin s. The receiver 'is preferably of rectangu ar cross section and provided with rounded (Fig. 2 or sharp (Fig. 4) corners. The bellows folds are formed of iron or steel plates 6 (or of cast iron plates etc.) whose inner and outer longitudinal edges are hinged or connected together in a similar manner. rounded by bending or otherwise of a pair of lates6 engage. with each other, while in ig. 7 these edges are provided with eyes 6,

' 6 through which a round rod 7 passes; the

the inner edges of the plates 6 lie freely against each other and are held together by a .1 single or a row of spring clamps 20, while the outer edgeshave hingelike supports, The single folds ofthe bellows so formed are separated from each other and held together by means of a ri id ring 8 made as shallow as possible. The rings 8 are preferably made of four parts firmly connected at the corners of parts opposite each other are so held to ether-by rods 9 (Fig.4) that the sides are re: ieved of inside pressure as far as possible sides comparatively s ight. system of stiffening rods 9 'on each ring 8 may be re laced a stiffening disk or-plate 10 Fig. 2 a so arranged at the middle level'of the ring 8; the plate may be connected to the Patented-Jan. 21, 1908. 5

' The p ates 6 are connected at the corners of the receiver in the same manner as the bel- 3 lows of a concertina, that is to say, by insertions made of'flexible material, which easily pucker and which are sufiiciently strong to withstand the inside pressure upon the small triangle produced by filling out the receiver. Rubber or rubbered fabric and the like is a suit-able material" for these insertions which are shown at 15 in Figs. 3 and 5. In order to relieve the insertions 15 as far as possible from inside pressure, the gaps in the corners,

when the latter are rounded as in Figs; 2 and V 3-may be covered with scale like plates 19 overlapping each other, which areconnected by hinges 21 to the ring 8 and can slide upon each other when the end corners 6 of the plates 6 a proach or move from each other;

When t e receiver'has sharp corners as in Figs. 4 and 5,-the flexible insertions 15 which are fixed to'the plates 6 by means of rivets 16 'or the like are surrounded, if desired, with- Wire gauzes 17 made as flexible as possible.

When the cross section of the receiver is round the sides of the latter are preferably constructed of several Z-shaped telesco ic rings 22 Fig. 9, the rings being stiffened y means of lates 10 or rods in, the manner shown in gs. 2 and 1 or the pressure may be transmitted to a su port or supports. by

' rollers as shown in Figs. 12 and 13.

respective parts of or even, as shown in Figs.

3 In order to prevent the loss of fluid (and consequently pressure) in the movable connections of the plates 6 and the rings 8,the

6,8 and -9, the whole of the inside surface of the bellows may be provided. with linings 14 v of rubbered fabric or the like.

The modification of the press shown in i Fig. 11 differs in that'the receiver 1 with the prising .rnovable press plate 2 is arranged at the top,

springs 26 being provided to raise this plate after each downward movement of same.
